MISSION: STS-84 -- 6th MIR DOCKING & SPACEHAB DM VEHICLE: Atlantis/OV-104 LOCATION: Pad 39A TARGET KSC LAUNCH DATE/TIME: May 15 at about 4:08 a.m. LAUNCH WINDOW: 7 minutes TARGET DOCKING WITH MIR: May 16 at about 10:39 p.m. TARGET UNDOCKING: May 21 at about 9:05 p.m. TARGET KSC LANDING DATE/TIME: May 24 at 7:53 a.m. MISSION DURATION: 9 days, 3 hours, 45 minutes CREW: Precourt, Collins, Foale, Noriega, Lu, Clervoy, Kondakova ORBITAL ALTITUDE and INCLINATION: 160 nautical miles/51.6 degrees NOTE: The countdown for launch of Atlantis continues on schedule for liftoff on Thursday. The 7-minute window opens at about 4:08 a.m. The exact launch time will be announced about 90 minutes prior to launch following final computation of the location of the Mir space station. Atlantis is scheduled to land at KSC's Shuttle Landing Facility at about 7:53 a.m. on May 24.

Last night, Pad 39A was cleared to load cryogenic reactants into the orbiter's power reactant storage distribution system. Reactant loading was completed on schedule. The liquid hydrogen and liquid oxygen reactants provide electricity for Atlantis and the crew while in space and drinking water as a by-product.

This morning, The orbiter's mid-body umbilical unit was demated and retracted into the fixed service structure. Also today, work is scheduled to activate the orbiter's flight controls and navigation systems and to prepare the shuttle main engines for propellant tanking.

On Wednesday, the rotating service structure will be retracted away from the launch vehicle at about 10 a.m. Loading of the external tank with cryogenic propellants is scheduled to begin at about 6:15 p.m. Wednesday.

Weather forecasters are currently indicating a 20 percent probability of weather prohibiting launch on Thursday. The primary concern is for cloud ceilings below 8000 feet. There is no concern for weather violations at the time of tanking on Wednesday evening. The temperature at the pad at the time of launch is expected to be about 69 degrees; relative humidity about 78 percent; clouds scattered at 5,000 and 25,000 feet; pad winds from the northwest at 7 knots; and no precipitation is forecasted.

The 24-hour and 48-hour delay forecasts indicate only a 20 percent chance of violation as well.
